PORTABLE PUMP.

SPECIFICATION forming part of Letters Patent No. 269,676, dated December 26, 1882;

Application filed March 23,1882. (No model.)

To all trlzom it may concern:

. Be it known that we, WILLIAM J. Jornvson, a citizen of the United'iSt-ates, residing at Newton, Massachusetts, and FRANK G. JOHNSON, a citizen of the United States, residing at Boston, Massachusetts, have jointly invented certain new and uselul Improvements in Portable Pumps; and we do hereby declare that the same are fully described in the following speci- IO fication and illustrated in the accompanying drawings.

This invention is in the nature of an improvement on the class of portablepumps illustrated in the patent granted to one of ns--Wm.

1 5 J. J ohnson-No. 30,480, dated October 23,

1860, and having an adjustable stirrup or footpiece to hold the barrel in a vertical position. By our present improvement the foot-piece is placed on the ground-level, and is hinged to the lower end of a connecting rod or brace, which at its upper end is pivoted to a clamp or collar adjustable up and down on the barrel. By this construction the operator stands in a natural position, with one foot on the hinged 2 foot-piece, and allows the barrel to incline toward him as the pivots at each end of the connecting-rod permit, so that the reciprocating stroke ofthe piston is in a directline from hisshoulder, and is effected with great ease. The 0 doubly-pivoted connecting-rod is also a. brace, being preferably made of two flat bars spread at the bottom, so as to give lateral support from the foot-piece to the barrel. A suitable stop is also provided to prevent the brace and foot-piece from receding too far from the barrel, and a spring tends to keep them in contact with it. The foot-piece folds beneath the lower end of the barrel when not in use, and the whole structure is, by its pivots and hinges, 4 made most compact.

Our inventions consist in the devices and combinations of devices-set forth in the appended claims. They are illustrated in the annexed drawings, in which- Figure 1 shows our improved pump asin use. Fig. 2 is an enlarged view of the pump, embodying the various improvements, and Fig. 3 shows a part of it folded for transportation or storage. Fig. 4 is a detail of the clamp, stop, &o.

A is the pump-barrel, designed to be inserted in a pail, B, or other water-receptacle,

as described in said former patent.

C is the piston-rod, made hollow within the barrel, and having a suitable handle for its re 5 ciprocation, whereby the valves are worked as described in said patent, and water drawn in and subsequently forced out through flexible pipe D and nozzle E.

Our invention relates especially to the sup- ()0 porting means for holding the pump in position during temporary use, consisting of the adjustable clamp F, the doubly-pivoted brace G, and the hinged foot-piece H, with which parts we usually employ the stop I and spring 6 J, about as shown.

The brace G is made preferably of two fiat metallic rods, pivoted at the upper end to the clamp and at the lower end to the footpiece, and spread somewhat at the bottom to give a lateral support or bracing. Lugs H on the foot-piece H, or equivalent slots, hold the rods G Grin place and receive the connecting-rivet,

forming a hinge to permit the foot-piece to fold beneath the barrel, as in Fig. 3.

The clamp F is shown as made of a single piece embracing the barrel, its ends, nearly meeting, beingdrawn together by a tighteningscrew, L, which holds it fast at any desired height on the barrel. A pin, K, in the clamp forms a pivot for the upper end of the connecting-braces Cr G,which enter a recess, or between ears formed on the clamp, as shown. A11 adjacent pin, I, forms a stop to prevent the brace from so swinging on its pivot as to carry 8 the foot-piece too far from the foot of the barrel. J is a spring, which is held in place by the stop I, or in anyother convenient manner.

It tends to press the brace toward the barrel and hold the pump in a "ertical position 0 against the side of the pail B when the operators foot is removed from the foot-piece.

It is obvious that the clamping-screw L may serve as the pivot for the upper end of the brace G G,and that some other stop, properly 5 located, may be substituted for the pin I.

The advantages of our improvement over the original Johnson pump are that the footpiece is on the level with the ground, so that the operator is in a more comfortable position, and no injury to the pail arises from contact of the foot-piece therewith. *e do not, however, claim broadly a portable putnp having a foot-piece at the level of the ground for the purpose of holding the pump in position for use, since the patent to Vose, November 15, 1S59, shows such construction. The patent to Douglas, dated July 10, 1877, shows such location of the foot-piece; but it is not hinged to the post or standard, nor is the upper end of the standard pivoted so as to swing to and from the barrel, but the arm, standard, and foot-piece protrude rigidlyand at right angles, so as to be extremely awkward in packing and in use. The patent to Prouty, dated October 29, 1878, shows at the ground-level a rigid footpiece of peculiar form at the extremity of a stirrup-rod, which is forked and pivoted upon the bulb or head of the barrel, but has no adjustabiiity up and down on the barrel, and neither a stop nor a spring to control the brace. Fixed pumps, designed to be bolted to the sink or platform through which the draft or conveying pipe extends, have also been braced in order to secure them permanently in vertical position, the braces being pivoted to a sleeve adjustable, not on the pump-barrel, but on the pipe through which the water is conveyed to it from the well or cistern. An instance of this is found in the patent to Douglas, No-

vember 25, 1873, the foot of each brace being bolted to the platform and the pump not portable.

We make no claim to the devices shown in either of the patents hereinbefore referred to; but

\Ve claitn as of our invention 1. A portable pump provided with a supporting rod or brace pivoted so as to fold conr paetly with the barrel, and having a hinged foot-piecc, whereby the pump is held in place by the foot of the operator, substantially as and for the purpose set forth.

2. A portable pn mp provided with a pivoted support or brace having a hinged foot-piece, whereby the pump is held in place by the foot of the operator, in combination with a sliding collar or clatnp, adjustable up and down upon the barrel, and carrying the pivot for the upper end of the brace, for the purposes set forth.

3. A portable pumphaving a pivoted brace with a hinged foot-piece, in combination with asuitable stop to restrict the movement of the brace, substantially as set forth.

4. The combination, with a portable pump, of a brace made of two diverging metallic bars pivoted at the upper end, so as to told with the barrel, a stop to prevent too wide a range of movement to the brace, and a spring adapted to press said brace toward the barrel, for the purposes set forth.

In testimony whereof we hereto a'l'fix our signatures in presence of two witnesses.
